Look at this series: 1000, 200, 40, ... What number should come next?
A). 2
B). 8
C). 14
D). 24
8
This is a simple division series. Each number is divided by 5.
Rule = (1st number / 5 = 2nd number) (2nd number / 5 = 3rd number)....
Now, (1000 / 5 = 200), (200 / 5 = 40), (40 / 5 = 8)...
So answer is a = 8.
